Action Communities
Action communities allow customers to perform traffic engineering without IP Transit NOC involvement. If you need any help using these communities please contact our NOC.
Blackhole Community
The following community is used to blackhole specific IP addresses. We only allow /32 prefix announcements to be blackholed.
| Action | Community |
| Blackhole (/32 prefix) | 64098:666 |
Action Community Format
AS64098 standard action communities are formatted as our ASN followed by a 4 digit action code. The only exception to this is our blackhole community.
The community string is formatted as follows:
| Field | Value |
| ASN | 64098 |
| Action Field (64098:Xxxx) | Action to take |
| Peer Type Field (64098:xXxx) | Peer types to act upon |
| Continent Field (64098:xxXx) | Continent to apply action |
| Region Field (64098:xxxX) | Region to apply action |
Field Value Options
The following values can be used to build a complete action community string.
Note: localpref values can not be targeted and should use a peer type, continent and region value of 0.
| Value | Action | Peer Type | Continent | Region |
| 0 | – | ALL | – | ALL |
| 1 | Prepend One Time | Transit | – | ACT |
| 2 | Prepend Two Times | Transit – Domestic | – | NSW |
| 3 | Prepend Three Times | Peers – Multilateral | – | VIC |
| 4 | Set localpref 80 | – | Australia | SA |
| 5 | Set localpref 90 | Customers | – | – |
| 6 | Set localpref 100 | – | – | – |
| 7 | – | – | – | QLD |
| 8 | Set no-export | – | – | WA |
| 9 | Do not export | – | – | – |

Information Communities
Information communities show where and how a prefix was learned and are useful for filtering and analysis of routing issues.
Information Community Format
Our information communities are structured in a similar manner to our action communities except they have 5 digits instead of 4.
The information community strings are formatted as follows:
| Field | Value |
| ASN | 64098 |
| Peer Type (64098:Xxxxx) | Peer type prefix learned from |
| Continent (64098:xXxxx) | Continent prefix learned in |
| Region (64098:xxXxx) | Region prefix learned in |
| POP (64098:xxxXX) | POP prefix learned in |
Field Value Options
The following values can be used to decode a complete information community string.
| Value | Peer Type | Continent | Region (AU) |
| 0 | – | ALL | ALL |
| 1 | Customer | – | |
| 2 | Peer – Multilateral | – | NSW |
| 3 | Peer – Bilateral | – | VIC |
| 4 | Transit | Australia | QLD |
| 5 | On-net | – | SA |
